LM Prestige Mid or Mid+

Why would a racquet feel so much better in a mid rather than a mid+. I know the spec's are different. Flex, weight and 93 vs 98 cm
head size. I added wieght as tarheeljohn posted but the Mid feels so solid. I was thinking of ordering the Mid and stringing it up with a 18 gague for a little more bite on the ball.
Wao

I agree that the mid felt very solid. I felt that with the mid plus as well. The only area that I felt they differed was for vollys, and since I will be playing more doubles this summer (after hip surgery) I went with the MP. If I was going to be playing mostly singles I would go with the mid.
